> Can't you buy old PCs for 20 times less than a (second-hand) modern PC?
You can, but it's basically a paperweight at this point (I doubt you can even find a recent OS that boots it). Whereas back in the day, such a computer allowed me to play AAA games, browse the web, watch movies, and use the MS office suite for work or studies. Just as the average today's computer.
There have been gains (engineering or scientific calculation benefit a lot from the additional available computing power), but for most user, the improvement is at best marginal (the games' graphics are better, but I doubt it makes kids this days enjoy their games more than what I did when I was 12) or even nonexistent (what's the productivity gains from Word 2021 compared to Word 2000 for a student writing a thesis ?).
You can still do all those things on the Pentium 4 (boot up Windows XP, install Morrowind, use MS Office 2000 or whichever version was current, watch The Matrix), but the cost to buy the PC is significantly less (even taking into account the second-hand nature of the PC).
It isn't comparing like to like to compare the cost of a modern PC to one 20 years old, with modern games, modern websites, modern Office products etc.
